Post Lab Questions hey hove to alloo i to go in and ou 1. Why is it necessary for the plasma membrane of our cells to be "selectively permeable"? 2. Why is it important that the solute concentration of the cytoplasm within our cells is the same the solute concentration of the extracellular fluid? 3. Case Study: After running a marathon, an individual is brought into the ER with severe hyponatrem amounts of water. This causes the amount of sodium in the blood to drop drastically and the am of water to greatly increase (blood becomes hypotonic). ia. Hyponatremia occurs when a severely dehydrated person rapidly consumes large If the blood circulating though the brain is extremely hypotonic, what effect brain cells? might this have on t What symptoms might this person exhibit? List a couple of health care professionals that may be involved in the care and person. (think short term and long term, educating patient, etc) 2 it'b imPorlont to prevent namfel Lt.Explanation / Answer
1. HYPOTONIC SOLUTION is a solution whose tonicity is less than that of plasma.
2. When HYPOTONIC SOLUTION passes through brain, in order to maintain homeostasis, water passes into the NEURONAL CELLS causing SWELLING OF NEURONS.
3. Thus hyponatremia ( hypotonicity of blood) may lead to CENTRAL NERVOUS SYSTEM symptoms such as ALTERED SENSORIUM, DIZZINESS and LETHARGY.
